Thanks in advance for your help with the 'NetworkManager' or any
other convenient tool that would operate on Squeeze so as to easily

Make sure you have NO definition for eth0 in /etc/network/interfaces and
that you have:
[ifupdown]
managed=false
in /etc/NetworkManager/NetworkManager.conf
If it still doesn't work after a restart[1] please attach both files.
[1] not sure why, but in some cases new configurations did not work
properly until a full restart
Or you can keep /etc/network/interfaces as you have it now and edit
/etc/NetworkManager/NetworkManager.conf to have
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=true
(And you have to restart Network Manager.)
I just tested both ways, to no avail.
At first, I must say that my system did not have any
NetworkManager.conf file in /etc/NetworkManager/
The only NetworkManager.conf file that could be found on this system was in
/etc/dbus-1/system.d/
I can see the same thing on this other machine still on Lenny, where I am
writing this from: no /etc/NetworkManager/NetworkManager.conf file either.
the man page for NetworkManager does not mention any such conf file. I did
not dare modifying /etc/dbus-1/system.d/NetworkManager.conf
But I tested creating an /etc/NetworkManager/NetworkManager.conf, with only
****************************
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
******************************
As a first trial, I had just written:
***********************
[ifupdown]
managed=false
*************************
in it. But maybe I should have modified permissions and owner ? Owner was
root and perms: -rw-r--r--
Besides, my /etc/network/interfaces file did not contain any definition for
eth0. Still, I tested removing any mention of eth0, to no avail.
Below is my 'etc/network/interfaces' file :
*************************************
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
*********************************************
The file in "/etc/dbus-1/system.d/" is useful (to systems) if you have
systemd installed.
Do you have network access?
With your current setup, "managed=false" and eth0 defined in
"/etc/network/interfaces" you can control eth0 with ifup and if down.
With "managed=true", you'd have to use NM to bring up or take down eth0.
